What is fret in weather?
The forecasts of reference crop evapotranspiration shown here are called FRET (Forecast Reference crop EvapoTranspiration), and are presented as the most likely depth of water (in inches) that would evaporate and transpire from a reference crop under the forecast weather conditions on a daily and weekly basis.
Why is EvapoTranspiration higher in summer?
Potential Evapotranspiration PET is higher in the summer, on less cloudy days, and closer to the equator, because of the higher levels of solar radiation that provides the energy for evaporation.
What causes Harr?
Causes. Haar is typically formed over the sea and is blown to the land by the wind. This commonly occurs when warmer moist air moves over the relatively cooler North Sea causing the moisture in the air to condense, forming haar.
What does haar mean in Scottish?

How long can fog last?
How long does fog last from fog machine? How long your fog juice will last depends on the wattage of your machine. One quart of fog juice will generally burn for six hours in a 400-watt compact fog machine (four hours in a low lying machine) and a 1,000-watt machine will burn for two hours.
What is the difference between mist and fog?
Fog and mist differ by how far you can see through them. Fog is when you can see less than 1,000 metres away, and if you can see further than 1,000 metres, we call it mist.

What is Eva transpiration?
Evapotranspiration is the sum of evaporation from the land surface plus transpiration from plants. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.
